Significance and Use

The viscosity of emulsified asphalts characterizes their flow properties and affects their utility at 50°C (122°F) or at other temperatures. An emulsified asphalt sprayability and workability is directly related to their viscosity for many applications types. The material must be thin enough to be sprayed yet thick enough such that it will not flow from the crown or grade of the road. For mixing grade emulsified asphalts the viscosity will affect its workability and resulting film thickness on the aggregate. This test method is useful to measure the apparent viscosity of emulsified asphalt at a temperature of 50°C (122°F) or another agreed-upon temperature. The preset temperature and rotational speed at 100 RPM allow for an automated and consistent determination of an emulsified asphalt viscosity within a short time.

Scope

1.1 This test method uses a paddle rotational viscometer to measure the apparent viscosity of emulsified asphalt with viscosities between 30 and 1500 mPa·s (centipoises) at 50°C (122°F). It is applicable to all emulsified asphalt described in Specifications D977 and D2397.

1.2 The values given in SI units are to be considered the standard. The values given in parentheses are for information only.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
